ABSTRACT:
A calcar trial includes a stem having a proximal end and a distal end, and a body. The body is engaged with the stem near the proximal end of the stem and is slidable with respect to the stem. A locking mechanism inhibits movement of the body with respect to the stem when desired. A collar extends radially outward from the stem to surround a portion of the body. The body and stem are configured so that the diameter of the calcar trial at a point between the collar and the distal end of the stem increases as the body is moved toward the distal end of the stem and decreases as the body is moved away from the distal end of the stem. The proximal end of the stem can include opposed notches that are egagable by a forked tool. A curved distal stem portion can be secured to the distal end of the stem.
